Air temperature was measured at 0.02 m (Ta_2), 0.15 m (Ta_15), and 1.3 m (Ta_130) above the soil surface. Soil temperature was measured at -0.10 m depth in the topsoil (Ts_10). Soil water content (swc) was measured in the first -0.15 m depth in the topsoil. Data on soil water content and temperatures at -0.10 m, 0.02 m and 0.15 m were collected by TMS dataloggers (TOMST, Prague, Czech Republic) which recorded data every 30 minutes and were installed one meter north from the plot center within each sinkhole. Air temperature at 1.3 m was measured by three point-dendrometers with integrated air temperature sensor (TOMST, Prague, Czech Republic) which were installed on three trees per plot at the breast height in thinning and control plots. They were oriented northwards to prevent direct sun exposure. Dendrometers were programmed to record air temperature every 15 minutes. Trees with dendrometers were 2.8 to 25 m distant from the plot center. Resolution of temperature sensors was 0.0625 °C and accuracy ±0.5 °C. Data processing methods: Data series were first graphically and quantitatively inspected. Statistical outliers and data points indicating obvious errors caused by sensor failures (e.g. unrealistic data or large spikes in variables) were detected with the ˈtsoutliersˈ function in the R package forecast (Hyndman et al. 2019; R Development Core Team, 2018) and removed. Diurnal temperature ranges (DTR) were calculated as the difference between daily maximum and minimum temperature; mean values were calculated from all recored data for the whole measurement period per plot. Raw soil water content data were transformed into SWC data using an equation for sandy loam soil provided by Wild et al. (2019). Daily minimum and daily maximum SWC values were extracted for each location. These daily SWC values were then used to quantify drought intensity at each plot, using relative extractable soil water (REW), computed as follows (Bréda et al., 2006; Granier et al., 2007): REW=(〖SWC〗_day-〖SWC〗_min)/(S〖WC〗_max-〖SWC〗_min ), where SWCmin and SWCmax are the daily minimum and maximum soil water content (m3 m-3). REW values vary between 1.0 (maximum soil water content) and 0 (minimum soil water content) (Bréda et al., 2006; Granier et al., 2007).
